Describe the process of action potential conduction and neurotransmission from one neuron to another, both electrically (including saltatory conduction) and chemically. Describe how a cell fires an action potential and be sure to address which structures are involved in neurotransmission. Discuss reuptake and enzymatic degradation (breakdown) in the context of the appropriate neurotransmitters.
Answer:
neurons are able to communicate through electrical impulses for example when a stimulus is detected the receptor cells transfer electrical impulses to the sensory neurons which is passed onto the relay neurons in the central nervous system and relayed to the motor neurons. the motor neurons travel with the electrical impulses which are transferred to the effectors to cause a response. However neurons travel and commu icate through synapses

which of the following would differ if you compared the same reaction taking place with and without an enzyme
a. the chemical energy of the reactants
b. the chemical change of the product
c. the energy required to the reaction
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.
Describe the transport properties of the loop of Henle and explain the interactions between the ascending and descending limbs
Answer:
The loop of henle is a part of the renal functional unit.
This handle has an ascending part and a descending part.
In the descending loop, the urine that is formed inside enters a hypotonia, since a large amount of water is absorbed and the concentrations of solutes in the urine decrease, thus generating a hypoosmolar solution, that is, with less molarity.
In the ascending loop of henle, the opposite arises, ionic channels appear that increase the concentration of solutes, this is how the urine that runs through the interior of the ascending loop of henle becomes hyperosmolar.
Hyperosmolarity is the increase in concentrations of solutes, and the increase in molarity of the solution, which in this case would be urine.
Explanation:
A very important fact is that urea is absorbed in the ascending henle loop.

Explanation:
During cellular movement which filaments will be the ones that are responsible for attaching and pulling the other filaments along?
Answer:
Myosin
Explanation:
Myosin are the major components of both muscle and non muscle cells in striated muscles which is responsible for contraction or movement that convert chemical energy (ATP) into mechanical work thereby generating force and movement.
During cellular movement , myosin filament will be the ones that are responsible for attaching and pulling the other filaments along because Myosin binds to actin at a binding site on the globular actin protein,it also have ATP binding sites which hydrolyses ADP to ATP , ATP binding causes myosin to release actin, which make actin and myosin to detach from each other thereby causing attachment and contraction of other filaments
o help create these gradients, there are a series of capillaries, branching from the peritubular capillaries and associated with the loop of Henle, collectively called the
Answer:
Vasa recta.
Explanation:
Vasa recta are a group of capillaries, branching from the peritubular capillaries and moves parallel with the loop of Henle. Vasa recta is responsible for the supply of blood to renal medulla in order to purify the blood from the waste materials such as salts, excess water and nitrogenous waste etc. Due to its movement with the loop of Henle, it slows down the blood flow which helps in the re-absorption of water.

You decide to focus first on Mutation 1 and Mutation 2.
The F' plasmid appears to "rescue" mutant strain 1 by restoring wild-type inducible expression.
The F' plasmid does not change the phenotype of mutant strain 2; there is still no expression of the lac operon.
There are three possible mutations that could lead to lack of expression: a super-repressor (Is), a promoter mutation (P-) or a mutation in the lacZ gene (Z- ). To determine the effect of introducing a wild-type F' plasmid into a bacterial cell with each of these mutations, you draw out the three possible scenarios.
F' l+ cap+
Determine the expression of the lac operon for each possible partial diploid and for the "unknown" mutation partial diploids (Mutation 1 and Mutation 2).
1. F' lac+/ ts
2. F' lac+/ P
3. F' lac+/ Z
4. F' lac+/ Mutation 1
5. F lac+/ Mutation 2
A. Inducible (wild type)
B. No expression (mutant)
Answer:
Super-repressor (Is) - Uninducible dominant
Binding region is modified by the protein called repressor which prevents the lactose to bind with it. Thus, even the lactose is present the repressor protein is bound to the promoter and can not be detach from it. Transcription is not inducible.
Promoter mutation (P)- - Uninducible recessive
Mutated promoter region inhibits the binding of RNA polymerase that leads to trranscription.
The lacZ gene ( Z-) is mutated - recessive while the normal LacZ gene (Z +) - dominant .
Inducible (Wild type) No expression (Mutant)
F' lac+/ Is No Yes
F' lac + / P- Yes No
F' lac + / Z- Yes No
F' lac +/ Mutation1 Yes No
F' lac+ / Mutation2 No Yes
Mutation 1 and F' plasmid - Inducible wild type
Mutation 2 and F' plasmid - Mutant no expression
What is better sexual or asexual? Reproductive

how gravity plays a role in the parts of the water cycle shown in this model.
Answer:
look dear i will explain
Explanation: It pulls precipitation down from clouds and pulls water down hill . gravity also moves air and ocean water. Gravity pulls denser air and water downwards,forcing less dense air and water o move upwards.
okay hope it works
Hit like
Answer:
Gravity causes precipitation in the clouds to fall to Earth. On the ground, gravity influences surface runoff, as water travels from higher to lower elevations. Gravity also influences groundwater because it pulls elements toward the center of Earth. Water, under the influence of gravity, seeps into the ground to form groundwater.

Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.
Answer: Option E.
All of these are used by parietal cells.
Explanation:
Parietal cells are found in the stomach and they produced gastric acid(Hcl)..
HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.
Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).
Therefore it uses channels, pumps, antiporter.
g Riboswitch is a mechanism of gene activity regulation by mRNA conformation. Riboswitch can regulate ______.
Answer: c. both transcription and translation
Explanation:
Riboswitchs are mRNA elements that influence the activity of genes certain genes by regulating same and are found in other organisms apart from humans such as bacteria, plants and fungi.
They regulate activity by binding to specific small molecules known as ligands thus causing a structural rearrangement that enables either transcription or translation to be modulated in the gene.

Professor George Palade’s elegant experiment to follow protein synthesis and trafficking, published nearly 60 years ago, provided us with a great deal of information and has been used as a tool by several investigators. If you had access to all the reagents needed to repeat the in vitro experiment, describe what you would need to do to see the progression of newly synthesized proteins and their transport in the cell.
Answer:
The interpretation including its particular topic is demonstrated in the following portion on the interpretation.
Explanation:
After experiments with Guinea Pigs, Palade transitioned to anything in vitro research in which sections of pancreatic tissue had all been subjected to a pulsed radioactive lysine for something like a shorter amount of time. The radiation leucine pulse must have been subsequently adopted with nonradioactive leucine, as well as the pieces have been fixed but instead analyzed besides electron microscopy as well as transmission line during some different points in time.Effects from either the radioactive elements with leucine throughout the reflective coating surrounding the tissue fragments formed autoradiographic particles.Such granules eventually passed forward towards the Golgi throughout corresponding different points in time, as well as subsequently towards the cell membranes, whereby they seemed equipped for induction as established zymogen granulates.PLS ANYONE IT'S URGENT Explain eubacteria ?

Applying ACh to the small intestine will cause a smooth muscle ______, which is through activation of ______ receptors.
Answer:
The correct answer is - Excitation; and Gi receptors.
Explanation:
ACh or acetylcholine is a secondary messenger that cause excitation by propagate the signal to the muscles from neurons. It is helps in transport the signal from the motor neurons to the muscles.
ACh release from the parasympathetic neurons and can directly excitation to the smooth muscle by binding to the Gi receptors or muscarinic receptors and activate them for excitation and contraction.
Thus, the correct answer is - Excitation; and Gi receptors.

Galactosemia is a metabolic disorder characterized by the inability to metabolize the sugar galactose. People with galactosemia suffer from liver, kidney, and brain damage among other symptoms. A gene mutation underlying galactosemia was identified by sequencing the genome of a person with galactosemia. What additional evidence would support the hypothesis that the mutation in the candidate gene causes the disease
Answer:
Genetic mapping for unequivocal identification of the potentially causative mutation
Explanation:
Galactosemia is a genetic disorder caused by mutations in the Galactose-1-phosphate uridylyltransferase (GALT) gene, which encodes an enzyme involved in the metabolism of galactose. Gene mapping is a technique widely used in genetics to identify the position of one locus a chromosome by using molecular markers to estimate genetic distances. Genetic mapping provides useful evidence in order to identify when a disease that is transmitted from parent to offspring can be associated with one or more genes and then determine which gene/s is/are responsible for this condition.
To study the fate of carbon during glycolysis under aerobic conditions, cultured cells are fed with 14C-glucose labeled in various positions. You use a radiolabeled form of glucose where the radioactive 14C occupies position 1. Which of the following is correct?a. The carboxyl group of acetyl-CoA and CO2 become radiolabeledb. The methyl group of acetyl CoA and CO2 become radiolabeledc. The carbonyl group of acetyl-CoA becomes radiolabeledd. The methyl group of acetyl CoA becomes radiolabelede. CO2 becomes radiolabeledf. I don’t have enough information to conclude
Answer:
D. The methyl group of acetyl CoA becomes radio-labeled
Explanation:
During the steps in glycolysis, the carbon at position 1, becomes C-1 in dihydroxyacetone phosphate during the cleavage of fructose-1,6-bisphosphate to dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Subsequently on isomerization of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate, C-1 of dihydroxyacetone phosphate becomes C-3 of glyceraldehyde-3-phosphate.
Furthermore, in pyruvate, the end product of glycolysis, C-3 is converted to a methyl group which then becomes the methyl group in the acetyl-CoA molecule produced from the oxidative decarboxylation of pyruvate.
Since the radioactive 14-C of radio-labeled glucose occupies position 1, it will become the methyl group of acetyl-CoA.
